PRINTING DEVICE.

SPECIFICATION forming part of Letters Patent No. 636,524, dated November"7, 1899.

Application filed April 16, 1898.

- zen of the United States, and a resident of the city, county, andState of New York, have invented a new and useful Improvement inPrinting Devices, of which the following is a specification.

My invention relates to that class of printing devices by whichimpressions are made on paper or other surfaces at regular intervals;and the objects of my improvements are, first, to afford facilities forthe proper adjustment of the different letters and numbers independentlyof each other in respect to the line to be printed; second, to providemeans for the insertion of complete lines or plates having surfacescapable of printing letters or designs'for the same purpose withoutinter fering with the before-mentioned arrangement, and, third, toprovide means for properly inking the printing-surfaces. I attain theseobjects by the mechanism illustrated in the accompanying drawings, inwhich Figure 1 is a plan viewof the apparatus, and Fig. 2 a longitudinalvertical section of the same on the line 1 2 of Fig. 1.

Similar letters refer to similar parts of the two views.

A designates a frame provided with a handle. In the middle of this frameare two rollers B B, mounted loosely on a shaft 0, which is stationaryin the center of frame A. The space between. the two rollers B B isoccupied by fianged belt-wheels D D, which are of even dimensions andsmaller in diameter than the rollers B B. These belt-wheels D D havecogs formed upon their flanges and are also loosely fitted on shaft 0 toallow of their revolving independently of each other, while the rollersB B are connected to each other on and near their peripheries by thechases T T (so styled because each performs the function of a printerschase) and plate U in such a way that their connection does notinterfere with the flanged belt-wheels D D. This construction provides arigid frame, styled hereinafter acylinder-frame, in which the flangedbelt-wheels D D, the assembling-bar G, and the type-bands D can beproperly mounted, the whole forming a rotary smart. 677,844. (No model.)

printing element which for convenience I shall allude to as a rotatableprinting-cylinder. Upon the belt-wheels D D are belted soft-rubber bandsD D, which I style typebands. These bands have on their outer surfacesprojections capable of printing numbers and letters, and said bands arealso stretched over an assembling-bar G, common to them all, which is sosupported by the two rollers B B that the plane of the type-faces ontype-bands D D when said type-faces are at F is tangent to theperipheries of the rollers B B. A furtherfunction of said assemblingbaris to hold the adj ustedband in the desired position through frictionbetween itself and the band. 7

To adjust the desired types of the typebands' D D in a line parallel tothe axes of the rollers B B at the point F, each of the flangedbelt-wheels D D is provided with a pinion H. Said pinions H H areloosely mounted on stationary shaft I and are sepa, rated from eachother by hubs or their equiw alent, allowing independent revolution ofeach through the agency of a spur-wheel K, mounted on shaft L andactuated by crank S. Spur-wheel K has a keyin its hub loosely engaging alongitudinal groove or keyway in shaft L, so that it can be freelyshifted along said shaft to operate any of the pinions II II for theadjustment of the corresponding typebands D D on their respectivebelt-wheels D D, and thus make any desired changes in the printing-lineat F. After this adjustment is perfected spur-wheel K is swung out ofengagement with the pinions H H on the fulcrums N N by the arms M and Mof shaft L and held out of engagement by finger R of arm M matchingnotch P of spring 0. This spring 0, which is secured at one end to frameA, serves also to hold spur-wheel K in engagement with that one of thepinions H II it is desired to operate.

The chases T T may be provided with permanent lines of type, the planeof their faces of course being tangent to the peripheries of rollers BB, as in the case of the bands D. The same may be the case with theplate U, bearing types or designs to be printed at regular intervals ona surface, with which the so-called printing-cylinder comes in contactwhen rotated by being pushed forward to roll on the same.

The type-faces and other printing-surfaces receive their ink through themotion of the printing-cylinder from ink-roller V in con- .tact with astrip of felt or other fibrous material fastened in a slit ofink-reservoir W, which is fastened to the extending end of frame A andis provided with bearings for the shaft of ink-roller V.

I am aware that prior to my invention printing devices have beeninvented operating to print impressions at intervals by rolling across asurface; but I am not aware that any of these devices are capable ofsuch adjustment as specified herein. Therefore, though I do not claimsuch a combination broadly,

I do claim as novel and desire to secure by Letters Patent- 1. In aprinting device, the combination of a main frame; a shaft journaled insame and a rotatable printing-cylinder, mounted upon said shaft,comprising a rigid cylinder-frame; belt-wheels within saidcylinder-frame, rotatable upon the said shaft; an assembling-bar andtype-bands, belted around the bar, upon said wheels, substantially asshown and described.

2. In a printing device, the combination of a rotatableprinting-cylinder, comprising a rigid cylinder-frame belt-wheels withinsaid frame, bearing cogged flanges; a shaft, common to said frame andbelt-wheels; an assembling-bar and type-bands, belted around the barupon the wheels and pinions adapted to engage the cogged flanges of thebelt-wheels; a shaft, common to all the pinions and means for turningsaid pinions, substantially as shown and described.

3. In a printing device, substantially as specified, having flexibletype-bands, adjustable by means of belt-wheels, bearing cogged flanges,operated by pinions; the combination with said belt-Wheels, flanges andpinions, of a spur-wheel, K, keyed free to move longitudinally upon ashaft into engagement with any one of said pinions and means, operatingto turn said shaft and adjust the said typebands, substantially as shownand described.

4. In a printing device, the combination of a main frame, carrying arotatable printingcylindeighaving adjustable type-bands,belted around anassembling-bar, upon wheels hearing cogged flanges and pinions inengagement with said flanges; an adjusting spur-gear adapted tocooperate with the pinions to adjust the bands and means, operating tohold said spur-gear into and out of engagement with said pinions,substantially as shown and described.

5. In a printing device, havinga rotatable printing-cylinder, carryingadjustable typebands; the combination of means for adjusting said bands;mechanism, actuating said means, movable into or out of its operativeposition and means for holding said mechanq ism in an operative, orinoperative position at will, substantially as shown and described.

In testimony that I claim the foregoing as my invention I have signed myname, in presence of two Witnesses, this 25th day of March, 1898.
